**Neo4jTools** enables agents to interact with Neo4j graph databases for querying and managing graph data.

## Prerequisites

The following example requires the `neo4j` library.

```shell
pip install -U neo4j
```

You will also need a Neo4j database. The following example uses a Neo4j database running in a Docker container.

```shell
docker run -d -p 7474:7474 -p 7687:7687 --name neo4j -e NEO4J_AUTH=neo4j/password neo4j
```

Make sure to set the `NEO4J_URI` environment variable to the URI of the Neo4j database.

```shell
    export NEO4J_URI=bolt://localhost:7687
    export NEO4J_USERNAME=neo4j
    export NEO4J_PASSWORD=your-password
    export OPENAI_API_KEY=xxx
```

Install libraries

```shell
pip install -U neo4j openai agno
```

Run the agent

```shell
python cookbook/tools/neo4j_tools.py
```

## Example

The following agent can interact with Neo4j graph databases:

```python
from agno.agent import Agent
from agno.tools.neo4j import Neo4jTools

agent = Agent(
    instructions=[
        "You are a graph database assistant that helps with Neo4j operations",
        "Execute Cypher queries to analyze graph data and relationships",
        "Provide insights about graph structure and patterns",
        "Help with graph data modeling and optimization",
    ],
    tools=[Neo4jTools()],
)

agent.print_response("Show me the schema of the graph database", stream=True)
```
